I wanted to come back to this list so now I have the time

When you started with the Space Wolves, you wanted to capture the theme of a 'pack feel'.
- Currently you have cheaper units under a 2+ initiative. This is fine
- They also have a special rule where they attain +1 to Double or Charge
Effectively you have removed the negative aspect of a initiative to an extent with no discernible negatives yet retained the cheaper troop cost.
The +1 to Double and the Charge (as I have shown via the various air assault builds with this list) are far from a disadvantage.
If I could suggest anything it would be the following:
Remove the Unblooded (or at least the Double move aspect - makes no sense why this part of the rule exists other than to get past the 2+ initiative) and look to promote the pack mentality. I suggested a rule once that I will repeat here as a reminder:
Space Wolves in an assault may count Supporting formations as part of their total number of units when determining formation size at combat resolution
What this does is promote a playstyle of supporting formations and enhances the feel that the force has the 'pack mentality' where they work in concert with each other. I know you may have a concern with troops not doubling with a 2+ initiative, but that is why you have the cheaper cost on these units - a rule should not be made to compensate for this.
Even the +1 on a Charge is too much as the air assault force sees no negatives to the cheaper troop costs. It just needs to be balanced a little more by upping the costs; probably in the area of air assaults overall or back onto the units.
That's it for now. I hope this helps a little with feedback.
